Attribute maps not working right for markersymbols in sgplot

I have a challenge in getting attribute maps to relate to markers symbols.

 

In the following graph I want different symbols for the group variables

FactorpltPNG.PNG

I have an attribute set that contain the group as value, ID and Markercolor, linecolor and Marker symbol.

I've been using this blog as an example

https://blogs.sas.com/content/graphicallyspeaking/2012/02/27/roses-are-red-violets-are-blue/

 

However I do not get the markersymbol to work in the program below. If anybody can spot my mistake or another reason why this does not work I would be gratefull. I need to use an attribute map as I want the colors and symbols to be consitent with different subset of the lithography. There are no warnings in the log.

Hi:
Why do you have symbol=circlefilled in your SCATTER statement? I suggest you just keep size=10px in your SCATTER statement for MARKERATTRS and allow the attribute map to be in control.

Also, be sure to use attrpriority=none when you want different markers (particularly when using an attrpriority=color style like htmlblue).

Thanks a million. Three poeple here have looked at this and not seen the symbol=circlefilled. Removing and everything worked.

 

The reason it was there was form the first version before we decided we needed more symbols.

I find it easier to debug graphic problems when one option is on one line such as:

proc sgplot data=plot aspect=1 dattrmap=Lith_attributes;
	scatter x=Factor1 y=Factor2/ 
            group=New_name 
            markerattrs=(symbol=circlefilled size=10 px) 
            datalabel=variable 
            attrid=lith
   ;
	refline 0 / axis=x;
	refline 0 / axis=y;
	xaxis min=-1 max=1;
	yaxis min=-1 max=1;
run;

Long lines of code may tend to obfuscate an option that doesn't appear in a "normal" length statement. Since there may be many graphic options on a single plot statement this is a tad easier to read. Also commenting out one option is easier.

Thanks ballardw. You are completly right. Just old bad habits I think in adding all in one line.
